To be fair I wear it and on some of the crappy lonewolf servers I do lonewolf. But i'm usually insurgent. And I always say a big 'alright guys!' when I join squads, and ask the SL where he wants me.

If I squad lead, I stop lonewolfing if the other guy responds.

I never lonewolf on what I call the good servers - PRTA/NwA.

There is still usually good gameplay on the other servers, but it's horses for courses - not everybody wants a disciplined, 2hr camping match as can happen on the teamwork servers and I respect that, but also tend to play accordingly myself in those ones.
